About OpenSSRF

The Standard Spectrum Resource Format (SSRF) defines standard data elements
for automated exchange of radio-frequency (RF) spectrum-related data.
SSRF is managed under the authority of DOD Directive 5100.35, Military
Command, Control, Communications, and Computers Executive Board (MC4EB) and

The SSRF specification is published and placed in to the public domain by
